Following an introduction that outlines the history and projects the future of gerontology, the authors offer insightful profiles of roughly 300 researchers, teachers, and practitioners in aging. North Americans are heavily represented, though gerontologists from Great Britain and the Continent are included as well. The dictionary can be read for an overview of the field, while cross-listings and a complete name and subject index make it an ideal reference. Each entry contains a professional and academic biography, along with citations and succinct descriptions of the individual's important contributions to the study of the elderly and aging.
